HESI A2 Vocabulary 2023 Questions
Question 1 of 5
Select the meaning of the word 'undulate' in the sentence: 'Each shiver made his muscles undulate beneath his skin.'
Correct Answer: A
Rationale: The correct answer is A: Ripple. In this sentence, 'undulate' is used to describe a smooth, wave-like motion of the muscles, which aligns with the meaning of 'ripple.' The word 'undulate' implies a continuous and flowing movement, resembling the gentle and rhythmic movement of waves. The other choices, shake, flatten, and unknot, do not capture the specific fluid and continuous motion described in the sentence. 'Shake' implies a more abrupt and irregular movement, 'flatten' suggests a completely different action of making something flat, and 'unknot' refers to the action of undoing a knot, none of which fit the context of the sentence.
Question 2 of 5
The breastbone may be called the ___________.
Correct Answer: D
Rationale: The correct answer is D: sternum. The sternum is commonly known as the breastbone in human anatomy. It is a flat bone located in the center of the chest, connecting the rib bones. The term "sternum" is derived from the Greek word "sternon," which means chest. The other choices (A: stelic, B: steres, C: sterol) are not anatomical terms related to the breastbone or chest structure, making them incorrect options in this context.
Question 3 of 5
Choose the meaning of the word 'persistent' in the following sentence: 'The elderly patient has been fighting a persistent cold.'
Correct Answer: D
Rationale: The correct answer is D: Lasting a long time. In the sentence, 'persistent' is used to describe the cold that the elderly patient has been fighting, indicating that the cold has been ongoing and enduring. This aligns with the definition of 'persistent' as something that continues for an extended period. Choices A, B, and C are incorrect because 'persistent' does not mean typical, harmless, or without a cure in this context. The key to selecting the correct answer is understanding the context in which the word is used and its meaning in relation to that context.
Question 4 of 5
Choose the meaning of the word 'sanctioned' in the following sentence: 'The professor sanctioned our field trip to the chemistry lab.'
Correct Answer: D
Rationale: The correct answer is D: Authorized. In this context, "sanctioned" means the professor gave official permission or approval for the field trip. This is evident from the sentence structure where the professor is allowing or permitting the trip. Choices A, B, and C are incorrect because they do not align with the meaning of the sentence. "Organized" (A) implies planning, "Deterred" (B) means discouraged, and "Neglected" (C) means ignored, none of which fit the context of the sentence.
Question 5 of 5
Which word describes a screen or filter?
Correct Answer: A
Rationale: The correct answer is A: Permeable. Permeable describes a screen or filter because it allows substances to pass through. Screens and filters are designed to allow certain particles or substances to flow through while blocking others. Choice B, Incendiary, is incorrect as it means causing fires. Choice C, Exuding, is incorrect as it means to discharge or emit. Choice D, Resilient, is incorrect as it means able to withstand or recover from difficult conditions. The key in this question is understanding the function of a screen or filter, which is to permit the passage of some substances while blocking others, making the term "permeable" the most appropriate choice.
